ORNAMENTAL EMBROIDERY.

Specification of Letters Patent.

Patented July 10, 19217.

Application filed June 29, 1914. Serial No. 848,023.

To all whom it may concern:

Be it known that I, RUDoLr Lone, a citizen of the United States, and a resident of Jenkintown, Montgomery county, Pennsylvania, have invented certain Improvements in Ornamental Embroidery, of which the following is a specification.

My invention relates to ornamentation efiected by embroidery stitching, and comprises an ornamental figure made of a plurality of needle threads which are disposed radially and superposed upon each other to form a raised knot or button-like ornamentation which may be, relatively speaking, of any size desired.

The production of the raised knot or button-like ornamentation constituting the novel character of embroidery forming the subject of my invention, is produced by a machine employing two oscillating needles vibrating in a fixed path in line with their position. By rotating the goods upon which the stitches are laid with respect to a predetermined center disposed at some point intermediate the eXtreme throw of the respective needles, the stitches laid by these threads are caused to cross each other and produce a raised knot, the height of which may be easily regulated by the operator; the machine being stopped when the stitching has been effected to the desired height. The diameter of the knot is regulated by the throw or oscillation of the needles, and their movement may be effected and controlled in the manner set forth in my application for patent filed December 12, 1911, Serial No. 665,395.

My present invention comprises the improved embroidery ornamentation as a new article of manufacture, the process of making the same forming the subject of a separate application filed December 19, 1914, Serial Number 878,096.

These and other features of my invention will be more fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is an enlarged plan view of a piece of fabric, showing the obverse side of the ornamental embroidery knot made in accordance with my invention; showing also the position of the needles, a presser foot and means for turning the fabric;

Fig. 2, is a plan View showing the reverse side of the embroidery ornamentation illustrated in Fig. 1;

Fig. 3, is a sectional view illustrating the manner in which the needles operate in the fabric to lay the stitches thereon;

Figs. 1, 5 and 6, are enlarged sectional views showing various steps in the formation of the ornamental knot, and Fig. 7, is a view illustrating a modification within the scope of my invention.

In the production of the ornamental embroidery forming the subject of my present invention, I employ a sewing machine with a pair of vibrating needles, such as shown at 1 and 2, which needles are set in line with each other and vibrate in a single plane coincident with the plane of their position. The machine in which these needles are mounted is equipped with mechanism that will enable the operator to turn the work with respect to a redetermined center while the needles are vi rating and laying the desired stitches; the movement of the fabric with respect to the vibrating needles being wholly under the control of the operator.

With the fabric so controlled, the stitches from the needles will be laid in a radial direction with respect to the predetermined center, and this center will be at some point intermediate thelimits of the throw or vibration of the needles. By this means, I am able to produce a novel form of embroidery which consists of a plurality of sets of raised stitches 3 and 4, disposed upon the fabric 5, which stitches cross each other as the fabric is rotated and result in the formation of a raised knot or button-like figure. The stitches 3 and 1 are less in length than the diameter of the ornamentation produced by the same, and by reason of the fact that portions of said stitches cross the predetermined center, a greater bulk of thread will be left there and the height of such center will naturally be raised.

All of the stitches showing on the face of the fabric have loops 6 on the under side of frame in which the fabric is stretched. This fabric moving device is adjustable so setting,

the same, and these loops are caught by a single shuttle thread 7.

The effect of this ornamentation is materially heightened by the employment of threads of different color, and the size of the knots is controlled by the throw of the needles.

The fabric is moved by means of a rota table member such as shown, for instance, in my application for patent filed Dec. 31, 1913, Serial No. 809,7 98, comprising a fixed carrier lOhaving a friction member rotatably mounted in said carrier with a ball bearing for the latter; the friction member engaging. the fabric and turning with the latterwhen the operator moves the tambour as to change the center of the same with respect to the throw of the needles and effect circular ornamentation of various sizes. The needles may also be set in different relations with respect to each other; changes in the throw of the shuttle being correspondingly effected. I

In order toaccommodate the raised center made by the stitches 3 and a during the formation of the same, the presser foot 12 is provided with an enlarged space 13 at the outer end of the slotted portion accommodating the needles. This presser foot is employed solely to hold the fabric while the needles are. in the same to insure proper coaction of the shuttle thread and is raised when the needles are raised; having no feeding or other moving effect upon the fabricwhich is wholly under the control of the operator.

Inithe preferred process of producing the I ornamental embroidery forming the subject of my invention, the raised knot or circular ornament is formed of continuous stitches from .two independent threads laid by a pair of vibrating needles upon the rotating fabric, which needles osc'illate or vibrate in a plane coincident with the plane of their so that in the formation of such knot or ornament stitches will be laid simultaneously from opposite sides of the same,

" and the completion of the ornamentation is .veryrapid. It will be understood, however, that an ornamentation of a precisely similar nature may be produced by the employment of a single needle oscillated with respect toa pieceof fabric that is rotated with respect to such oscillating needle where the'center of rotation is offset with respect to a central point intermediate the throw of the needle; such for instance as the form shown in Fig. 7. My claims, therefore, are to be con'strued as broadly covering the-peculiar form of ornamental embroidery which I have produced, whether the same isv produced by 'a single thread laid by a single vibrating needle or by japa-irj off independent threads laid'by a pair of vibrating needles; in each case the stitches laid partially crossing each other at the center of the figure formed, in the manner indicated in the drawings, and the stitches in each instance having loops on the under or reverse face of the fabric which are caught by a single shuttle thread.

I claim:

1. An embroidery seam as a new article of manufacture, consisting of a piece of fabric having a plurality of radial stitches displayed thereon, said stitches crossing each other at a predetermined center and each stitch partially overlapping a radial stitch substantially diametrically opposite therefrom, all of said stitches being disposed to form a raised figure substantially circular in outline.

2. Embroidery ornamentation consisting of a piece of fabric having a plurality of sets of radially disposed stitches on its face formed by continuous needle threads, each set of stitches differing in color, which stitches cross each other at and are disposed around a predetermined center common to the several sets of stitches, the stitches of said needle threads producing a raised figure circular or substantially circular in outline.

3. An embroidery seam as a new article of manufacture, consisting of a piece of fabric having an annular row of stitches formed by a continuous needle thread radially disposed, the inner ends of said stitches partially overlapping stitches diametrically opposite therefrom at a predetermined center, the stitches of said needle thread producing a cone-shaped figure having a substantially circular outline.

l. An embroidery seam as a new article of manufacture. consisting of a piece of fabric having a plurality of annular rows of stitches formed by continuous needle threads radially disposed, the inner ends of each row of said stitches partially crossing each other at a predetermined center, the stitches of said needle threads producing a cone shaped figure having a substantially circular outline.

5. Embroidery ornamentation as a new article of manufacture, consisting of a piece of fabric having a plurality of radial stitches displayed thereon, said stitches crossing each other at a predetermined center, and each stitch partially overlapping a substantially diametrically disposed opposite stitch, all of said stitches being disposed to form a raised figure substantially circular in outline and having loops on the under side of the fabric which are caught by a single shuttle thread.
